“After 3 1/2 years, we have decided to close Water & Wall,” said the Facebook post. “We hope you’ll visit us at Kyirisan and Chase the Submarine. We have loved being a part of your lives.”

Water & Wall served its last dinner customers last night, the Washington Post’s Tom Sietsema said on his “Ask Tom” chat today.

A year ago, during an ARLnow.com-organized panel discussion on the local restaurant industry, Water & Wall owner and acclaimed chef Tim Ma was asked about keeping customers coming back after the initial excitement of a restaurant’s opening.

“Everybody was coming through the door on day one, two years later, it’s all about retention,” Ma said. “Staying relevant is probably the hardest thing. There are so many new restaurants opening, so many different areas coming back to life, staying relevant is hard.”

The restaurant has previously launched limited-time, “pop-up” menus, offering new dishes for diners to try. It brought on a new chef in June.
